In this detailed tutorial, I'll show you how to paint on freshly plastered walls like a pro with my tried-and-true methods and insider insights. Learn everything you need to know about painting new plaster, from the necessity of preparation to choosing the perfect paint and mastering application methods.
Instructions For Applying Paint On New Plaster
Putting A Finishing Coat On Fresh Plaster
Drying Time For Plaster Is About Three To Four Weeks, Or Until The Desired Colour Is Achieved.
A wide range of elements affects how quickly wet plaster dries. Most fresh plaster only needs 3-4 weeks to dry, but you can be sure by ensuring there are no dark areas on it.
- In relatively warm and dry conditions, plaster can dry in 2 weeks, but in colder or more humid settings, it can take six weeks or longer. The amount of time required also depends on the type of plaster and the number of coatings applied.
- A newly plastered wall will have a uniformly dark hue. There will be lighter and darker spots as it dries out. Wait to start painting until the entire wall is covered in a single light colour.
- Painting over wet plaster will only trap the plaster's moisture under the paint, which can lead to mould growth.
Create A Mist Coat By Combining Three Parts Water With One Matte Emulsion Paint.
You may find matte emulsion paint at any hardware store, paint retailer, or home improvement centre. Create a diluted mist coat by combining water and matte paint that is one shade lighter than the colour you intend to use on the wall.
- Try applying a mist coat first to achieve a durable finish on your walls with less effort.
- The mist coat should be painted with emulsion paint, but you should choose a less expensive paint than the top coat.
- Mist coats made with oil or vinyl-based paints will not adequately bind with the plaster or enable the plaster below to breathe, so use caution when choosing your paints.
Cover The Floor And Nearby Furniture With Dust Blankets.
Protect the floors and furniture from drips and spills by laying down canvas or plastic drop cloths. Since the mist coat is watered down and more likely to splash, it creates more of a mess than regular paint.
- Get the furnishings out of the room you'll paint. When you can't remove a huge piece of furniture from a room, cover it and move it as far away from the walls as possible (towards the centre of the room).
Paint Tray, Ready For The Mist Coat.
Pour in enough mist coat to reach the bottom of the paint pan. A tray of between 7 and 12 inches (18 and 30 centimetres) in width and depth will work for your roller.
- If you're painting a room with a 7-inch (18-centimetre) wall, use a 12-inch (30-centimetre) roller. Wall rollers range in size from 7 to 12 inches (18 to 30 centimetres); choose the best size.
Use A Foam Paint Roller To Apply The Mist Coat To The Wall.
Use the slanted side of the paint container to spread paint across the roller evenly. Apply it to the wall using lengthy, downward-facing strokes using a rolling pin. If you are right-handed, you should work from left to right, and if you are left-handed, from right to left.
- The mist coat will begin to dry rapidly because of the high absorption rate of the plaster. If you don't want an uneven coating, be careful to roll away any drips right away.
It would help if you Waited 24 Hours Before Painting Over The Mist Coat.
It's important to wait until the mist coat is dry and absorbed into the fresh plaster before applying a top coat, even though you can touch it after an hour. You can skip the second mist coat application.
- The drying period of a mist coat, like that of plaster, is affected by environmental factors such as temperature and humidity. To be safe, let the mist coat dry for an entire day.
Applying The Top Coats
The Top Corner On The Non-Dominant Side Is Where You Should Begin.
If you are right-handed, begin at the upper left; if you are left-handed, at the upper right. Working toward your stronger hand will help you create less mess while painting.
- If you are right-handed, you may paint the wall more efficiently and with fewer drips and smudges by beginning in the upper left corner and working in a left-to-right motion.
- A high-quality water-based top coat should be used to ensure a beautiful surface on the new plaster. If you spend more on paint, you will need to do less painting.
Paint All The Crevices Using A 4 In (10 Cm) Paintbrush.
Paint the vertical wall slats in the corners from top to bottom. The horizontal corners between the wall, ceiling, and floor should also be painted in the same direction.
- If you are painting near a previously painted wall that you don't want to cover over, take extra precautions. If you need more clarification about your brushwork, you can apply blue painter's tape to protect the corners of adjacent walls.
- Using a roller to fill in the rest of the wall will be much simpler and quicker after this "cutting in" process.
Use The Roller To Finish Off The Wall.
Cover the upper half of the wall first by rolling in straight lines along the vertical plane, then do the same for the lower half. If you are right-handed, you should work from left to right, and if you are left-handed, from right to left.
- Remember to inspect your work for any streaks or splotchy areas. Smooth out the bumps with a quick rollover.
Wait 6 Hours Or Overnight For The First Application To Dry.
The recommended drying time for a first application is 6 hours, but if you still need clarification, wait till morning. If you let the first coat dry completely, you'll be able to see where it's uneven and fix it with the second.
- If you're in a hurry, skip waiting for the first layer to dry and paint over it. If you wait until the first coat of paint is dry before applying a second, the final result will look much more polished.
Use The Same Technique You Used For The First Coat To Apply A Second.
Proceed from top to bottom and in the direction of your dominant hand. If there are spots that still look naked after the first layer, you should give them more paint.
- In most cases, a smooth, even coat of paint is required to cover the plaster. In this case, the quality of the top coat paint makes a big difference because a better finish requires fewer layers of paint than a lower-grade paint would.
Wait 24 Hours After Painting Before Hanging Anything.
The drying time of paint typically takes less time. However, err on caution and give it at least 24 hours to dry.
- No further work is required once the plaster has dried and the proper steps have been taken to seal and paint the walls. The top coat may begin to flake if you make a mistake, such as not allowing the plaster to dry long enough.
Can I Ruin My New Plaster By Painting It Too Soon?
Have you painted over freshly plastered walls before they could dry? You probably already know this because it has begun to peel off. The plaster has been "stuck" between the paint coat because water evaporates.
The bad news is that you'll have to scrape off the fresh coat of paint if you want to avoid this problem. A paint scraper would work well for this purpose.
How To Paint Over Wet Plaster Walls?
Painting interior surfaces, such as wet plaster walls, requires working in a well-ventilated location due to harmful vapours. If you need fresh air while working indoors, crack a window; don't leave it open too long, or condensation may form on the walls.
When using primers or sealants, be sure to follow the directions provided by the manufacturer. Paint may bubble, split, or flake if not applied properly, creating an uneven appearance.
Paint chips easily and peel off wet plaster walls. Many things can contribute to this, including insufficient preparation, defective materials, and a lack of suitable drying time between applications. Use high-quality products meant for plaster walls, smooth the wall's surface before painting, and give each layer plenty of time to dry to avoid this problem altogether.
You may have streaks or other imperfections if you don't use enough paint to cover the surface evenly. It's also possible if your brush strokes are too concentrated in one area. To avoid this problem, use a generous amount of paint on each stroke.
Blistering or bubbling can develop when the air becomes trapped between wet paint layers. Too much brushing pressure drives air into the wet layer below, causing the problem. Applying gentle pressure will ensure that no air bubbles are trapped under the wet paint and prevent this from happening.
Plaster drywalls often have problems with paint that cracks or flakes due to exposure to too much moisture. Water damage can be avoided by ensuring that all cracks in the plaster, drywall, windows, and doors have been sealed. Discolouration and wetness are further indicators you should look for in these spots.
When It Comes To Painting Fresh Plaster, How Can I Cut Costs?
New plaster can be painted for less money if you do it yourself. You should be fine with painting over freshly plastered walls as long as you wait the recommended period for the plaster to dry out entirely.
Painting is a labour-intensive job that can take you far longer than a professional painter or decorator with experience.
A professional painter can finish a four-bedroom house in seven to ten days, but it will take you longer because you will likely only be able to work on it in the evenings and on the weekends when you are not at work.
You may want to hire a professional if time is of the essence, but if you can be flexible, you can save a lot of money by going through this method.
Does Plastering Before Painting Require A Professional Builder Or Painter And Decorator?
Hiring a professional decorator is unnecessary if you're comfortable with your do-it-yourself skills and skilled with such projects. You may always hire a professional to complete the process, but you shouldn't feel obligated to do so if you'd rather try your hand at it.
Again, it's better to be patient and let the plaster cure completely before painting it, or else you'll have to redo the whole thing.
